myfabrik: online storage

Currently in beta, myfabrick.com is an online storage and shared storage app that is no-charge. As I have mentioned previously, data back-up, storage & sharing is picking up as a service to offer, especially for media files. RBS is an ISP favorite. I was wondering if you couldn't tweak the Amazon.com S3 API to use it's computing grid storage as your backup. S3 is certainly being used as a media storage device, as this post reveals. (One goober does the monetary calc on using S3 for home backup here.)
